Colour measurement for high visibility textiles

45°:0° geometry measurement solutions to measure the colour of high visibility textiles

High visibility textiles must be measured with a 45°:0° geometry spectrophotometer to meet the international standard EN ISO20471 and ensure that they perform their function. The fluorescent colours used ensure that they stand out in any environment against any background, typically red orange, yellow, and yellow/green, and protect the wearer by ensuring that they stand out. Production that meets these standards is therefore critically important for protecting lives. Failure to do so may have tragic consequences. Optical brightener is used, absorbing energy from outside the visible spectrum and emitting it within the visual spectrum making these garments appear brighter than clothing without.

Konica Minolta offers an instrumental solution, to ensure that high visibility clothing manufacturers remain compliant, and a software that can be used for capturing, analysing, reporting, and storing measurement data.


Our expert teams can advise you in establishing measurement processes that meet the requirements of the industry.

The Konica Minolta Measuring Instrument CM-25cG is a 45°:0° portable spectrophotometer with a user-friendly interface, rechargeable battery, and a sample viewer window for precise alignment of the measurement aperture. The instrument requires little training and can measure directly into the measurement software or into its memory for downloading into the software later.

Our extensive network of local service facilities will maintain and calibrate your device every year to ensure that the unit remains traceable to international standards.
